Abstract: COMPOSITE BEARING STRUCTURE OF ALTERNATING HARD AND         SOFT METAL, AND PROCESS FOR MAKING THE SAME                     ABSTRACT OF THE DISCLOSURE        A bearing structure having a substrate and a bearing surface of alternating, spaced, hard metal and soft metal areas is disclosed.  The hard metal is metallurgically bonded to the base metal substrate by rapidly melting in a predetermined pattern a powdered hardfacing composition disposed on a bearing precursor surface of the base metal substrate. The melting is accomplished by scanning with a laser beam, or like high intensity, concentrated energy source.  The melt is allowed to solidify rapidly.  Gaps formed between isolated areas of the solidified hard metal are filled with a melt of a soft metal.          After solidification of the molten soft metal, the resulting composite structure is machined to a desired depth to provide the composite bearing surface.

Abstract: ABSTRACT     The method for expanding tabacco lamina comprises contacting the tobacco with an organic expansion agent, heating the thus contacted tobacco in a closed first vessel so that the temperature of the agent is above the boiling point of the agent at a lower release pressure, and suddenly  venting the first vessel into a second vessel which is at said release pressure prior to the venting.  By this means the fill volume of the tobacco is increased by a least 50%.

Abstract: ACOUSTIC DIRECTION IDENTIFICATION SYSTEM     Abstract A system insensitive to non speech sounds utilizes a pair of spatially separated microphones to obtain the direction of origin of speech signals from a common sound source.  The speech signal from each microphone is transformed into a pulse representative signal having a rapid increase responsive to pitch peaks of energy from the sound source.  The cross correlation of these pulses accurately reflects the phase relationship between the speech signals arriving at the microphones.  The cross correlation is implemented as time interval histograms which are periodically read to identify the direction of the common sound source.

Abstract: ABSTRACT OF THE INVENTION           A mold and process for integrally forming from a selected material a helical shaped device which includes an axial member (33) integrally joined with a helical shaped flight member (41) is disclosed.   The  helical  flight  member  (41)  extends  a  selected radial distance from the axial member (33) and encloses up to 360 degrees of the axial member. The mold has a center operating axis (26) and includes a first section (20A) which partially defines an elongated cavity portion (34A) which forms a portion of the axial member  (33).  The first section (20A)  further defines a helical surface  (36A) which is disposed coaxially around and along  the center axis (26) and extends a selected distance radially from the center axis for an amount of rotation no greater than 360 degrees. This  surface  forms  one of  the  front  and back surfaces of  the helical shaped flight member (41).  In a similar manner, a second section  (20B)  is  adapted  for  reciprocating  movement  along  the center axis (26) between an open and closed position with respect to  section  (20A).   The  second  section  (20B)  also  defines  the elongated cavity portion (34B) and a helical shaped surface (36B) disposed around the cavity portion of section (20B).  The helical shaped surface of section (20B) forms the other one of the front and back surfaces of the helical shaped flight member (41), such ehat  when  the  two  sections  (20A  and  20B)  are  in  the  closed position,  the helical surfaces of each section of the mold are parallel to and are maintained a selected distance apart.  Thus, the two mold sections define a substantially enclosed cavity having an elongated axial portion and a helical shaped flight portion with a selected cross-section.  It is this cavity when filled with a selected liquid material that may be cured such that it holds its shape that forms the helical shaped device.  At least one of the two sections (20A and 20B) define a gate or port (48) which extends from the outside of the mold to the internal cavity such that the selected  liquid  material may  be  transferred  into  the  interior portion of the mold for forming the helical shaped device.  In a preferred embodiment, there is also included a center rod member (62) which is coaxial with the axial cavity (34A) and operates so that when withdrawn from the cavity it provides an aperture in the resulting  axial member  (33)  of  the helical  shaped  device.   In addition, the mold and technique may be used to form helical shaped devices having more than one flight member so long as each flight member does not overlap another flight member.

Abstract: DIGITAL I2t PICKUP, TIME BANDS AND TIMING CONTROL CIRCUITS FOR STATIC        TRIP CIRCUIT BREAKERS.            ABSTRACT OF THE DISCLOSURE   Digital implementation of the overcurrent determination and time delay before tripping in a static circuit breaker trip unit allows the trip unit circuit to be manufactured in a single chip configuration.  The signal after A/D conversion is compared within a magnitude comparator to determine pickup.  A pulse stream proportional to the square of the overcurrent signal is developed by multiplying the outputs of two magnitude comparators which compare the A/D level with a continuous binary count.  The time delay determination is obtained by means of 3 cascade connected divide by two counters with their outputs connected to a data selector, or by a rate-limiter circuit which uses a fixed frequency to gate a pulse stream proportional to the overcurrent level squared.

Abstract: ABSTRACT OF THE DISCLOSURE         A master tape and a slave tape are driven so that successive portions of each are brought into substantial contact with successive portions of the other at a printing station.  A printing magnetic field is applied to such successive portions while they are in substantial contact with each other at the printing station, so that data on the master tape is copied onto the slave tape and the slave tape becomes a copy of the master tape.  A single master tape can thus be employed to produce a plurality of copies.  A counter counts the number of copies thus produced, and an indicator provides an indication corresponding to the remaining life expectancy of the master tape.

Abstract: ABSTRACT       A method of offline personal authentication in a multi-terminal system uses a secret user PIN, a secret key and other nonsecret data stored on a customer memory card and a nonsecret validation value stored in each terminal connected in a network.  The technique of "tree authentication" is used which employs an authentication tree with an authentication tree function comprising a one-way function. An authentication parameter is calculated as a function of a personal key and a user identifier read from the user's card and the PIN entered by the user.  The calculated authentication parameter is mapped to a verification value using the one-way function to the root of the authentication tree.  The verification value obtained by mapping the calculated authentication parameter is then compared with a global verification value stored at the terminal.  If the comparison is favorable, the system is enabled for the user; otherwise, the user is rejected.
